Theoretical study of different fabrication techniques of ballistic electron wave-guides

A theoretical study of the ballistic conductance in electron wave-guides created by deep mesa etching from quantum-well structures for three different cases: continuous-gate, top-gate and side-gate. The continuous-gate device provides a periodic quantized conductance output and can be of potential use as a discrete device in high-speed analogue to digital conversion.
